Description

Airtight continuous filter
The present invention relates to a kind of airtight continuous filter.More particularly, relate to that a kind of both to have had the unit volume filter area big, filter medium both sides pressure reduction is big, keep certain filter cake thickness, filtering rate is big, and the separative efficiency height again can serialization production, can also closed-loop operation be suitable for simultaneously containing selecting and send out the property smell, or/and need the filter of the material that pressurization separates.
As everyone knows, equipment for separating liquid from solid is an indispensable unit operating equipment in the industry such as chemical industry, metallurgy, coal, mine, medicine, weaving, papermaking, food, environmental protection.Up to now, existing separator is concluded and is mainly included the film separation and do not have membrane separation device, wherein have membrane separation device to be divided into: pressure filter, for example: sheet frame or box pressing filter, tubular type pressing filter, close press (claiming pressure leaf filter again), ultrafiltration membrance filter machine; Vacuum apparatus, for example: rotary drum filter, folder end filter, leaf-type filter, disc type (polydisc, single-deck) filter, bag type filtering machine, tubular filter; Filter centrifugal, for example: 3-foot (top discharge) filter, top suspension (bottom discharge) filter, 3-foot (scraper bottom discharge) filter, body formula (continous way) filter.
Above-mentioned various equipment for separating liquid from solid all has advantage and unsurmountable inherent shortcoming separately.For example, flame filter press is the widest a kind of filter of present purposes; Because of its unit volume filter area bigger, it imposes on the pressure differential of filter medium both sides can be greater than 760mmHg, this is just much bigger than the pressure differential of vacuum filter, and filter cake thickness is generally between 30mm~40mm, more stable, but its defective is that up to the present it can't filter in serialization, and every filter is once, take long to material loading, discharging, filter wash cloth, thus the volume that it is intrinsic advantage little, that separative efficiency is high has weakened; And its filter cake thickness is subjected to the restriction of filter frame thickness, is difficult to change, so its filtering rate is a process of successively decreasing, promptly speed is very fast at the beginning the time, but runs material easily, slows down along with the increase of filter cake thickness; The filter cake moisture content is also higher; Even blow also of no avail with compressed air.If with the filter cake attenuation, though can solve the problem that improves filtering rate, the time of loading and unloading is more frequent, and separative efficiency is poorer.In addition, this device is incomplete closed filter, and this certainly will cause and be difficult to be suitable for to contain volatile flavor, or/and need the separation of the material that pressurization separates, work situation is abominable, labour intensity strengthens thereby make.
